Hi all, I plan to play mp3 CDs and was wondering if the interface to navigate the folders/mp3s was much different in the TCH without nav compared to the TCH with nav.

I have a handheld GPS (TomTom ONE) and would like to save the money and get the TCH without nav. The lack of FE charts kind of bums me out but I'm not sure if that's worth the extra $$

Thanks for any info!
